1 Claim.

This invention relates to means for loosening or tightening closures such as the covers of jars or other containers.

It is well known that, particularly on fruit jars V or the like, on which the closure is screwed on, it is often very difficult to turn said closure to tighten or open the same.

The object of this invention is to provide, as hereinafter described, means of this character which will be strong, durable, and simple in construction, and eflicient in the use thereof as well as economical to produce.

My invention is illustrated in the accompanying drawing'in which: i

b Figure 1 is a plan view, in elevation, of a jar closure comprising my invention.

Figure 2 is a side view in elevation thereof.

Figure 3 is a similar plan'view illustrating one form of a tool, included in my invention, as applied to'said closure for actuating the same.

Figure 4 is a side view in elevation thereof.

As shown in the drawing, my invention is illustrated in connection with a jar closure of common form comprising a sheet metal body 5 having a screw thread 6 formed thereon, and a sealing flange 1 extending from the front edge of said closure.

The object of my invention is accomplished by providing eng'ageable means on said closure, and

a tool to be used in connection therewith as follows:

The said closure is provided with a boss 8 on the top thereof and a peripheral groove 9 in said cover adjacent the said top. The said boss may 5 be'constructed in any suitable manner, such as by forming the same integrally with the closure or forming the said boss separately and securing it thereto.

The said tool comprises a ring. shaped portion 0 Ill having a boss engaging portion ll. This tool may be constructed of wire which is twisted together to provide a handle portion l2 that may be secured in a handle l3.

In the form shown, the said tool is formed of a single length of wire twisted, as above described, 5 and shaped to provide a boss receiving recess M.

It will be noted that the boss engaging member, or a portion thereof, extends parallel to the ring portion andabove the plane of said ring.

tion will engage the groove 9, thereby retaining 20 the tool firmly in engagement with "the closure during the operation thereof.

It will be understood from the above description that, in addition to providing means for tightening or loosening the closure, I have also 25 provided means for retaining the above described tool securely in engagement therewith so that it cannot slip off from the said closure while force is applied thereto.

I claim:

In combination with a closure having a peripheral groove in the side and a single boss extending from the top thereof; a tool having, as an integral part thereof, a ring shaped portion adapted to engage said groove, and a boss engaging portion on a plane with the top of said cover and extending inwardly from said ring portion in position to engage said boss at two sides thereof.

LOUIS PALMERI.
